1
Q

Kidney location
What surrounded by
Relative to adrenal glands

A

Retroperitoneal

Surrounded by perirenal fat which is enclosed by renal fascia…pararenal fat surrounds the renal fascia

Right is slightly inferior and MORE susceptible to injury because less protected

Adrneal glands are superior

2
Q
Cortex
Medulla
Papillae
Minor and major calyes
Pelvis 
SInus
A

Cortex - outer part with glomeruli for blood filtration…extend into medulla as renal columns

Medulla - inner portion containing pyramids that contain tubules for water resorption

Papillae - apex of renal pyramids and extend into minor calyx

Minor clayx - revieve fluid from single papilla

Renal pelvis - from multiple major calycis…continues as urteres

Sinus - central cavity containing minor, major calyces, renal pelvis fat and lymphatics

3
Q

Blood uspply

A

Each segmental artery divides into interlobar arteries that ascend in columns to CM junction…they branch into arcuate arteies that run parallel to interface…interlobular provide the affarent arterioles to each glomerulus

4
Q

Ureters - where to look for stones

A

Narrowing of pelvis
Where ureter corsses common iliac arteyr bifurcation
Where it enter bladder

5
Q

Female and amles ureter diff

A

Female - corssed uspriorly by the uterine artery

Male - by ductus deferences

6
Q

Control of bladder

A

Majority of muscle in urinary bladder is detrusor innervated by PS fibers (S2-S4)

Internal urethral sphincter - sympathetic fibers

PS fibers elicit contration of detrusor AND inhibit the internal urethral sphincter
